Area Forecast Discussion
National Weather Service Sioux Falls SD
529 PM CST Sun Feb 17 2019

.SHORT TERM...(This evening through Monday)
Issued at 320 PM CST Sun Feb 17 2019

Light snow has shown signs of diminishing across the area this
afternoon, but the expectation is that light snow or flurries will
linger at least through the early night time hours as a vort tail
behind the exiting upper level low pulls across the region.
Additional accumulations will generally be a half an inch or less.
Colder air will begin to filter in behind the exiting system, so
temperatures will be a little cooler tonight - dropping mainly
into the single digits.

Canadian high pressure builds into the region on Monday, keeping
cold temperatures across the area. Highs will be in the teens.

.LONG TERM...(Monday night through Sunday)
Issued at 320 PM CST Sun Feb 17 2019

The active weather pattern continues on Tuesday as another upper
level trough tracks into the Northern Plains. There are still some
differences among the models with regard to both upper and surface
level features, though there is a fairly good consensus on the
potential for moderate snow accumulations over our area for Tuesday
afternoon into Wednesday afternoon. As in the recent event, winds
look to be relatively light so blowing snow should not be an issue.

Although there will be some gradual moderation in temperatures for
the remainder of the week, readings still look to be below normal
for this time of year. And once again, snow looks to move back into
the area for Thursday night through Friday. Although there are model
differences, there will be another potential for light to moderate
snowfall accumulation across the area.

in most locations.

Ceilings may slowly improve through the day on Monday.
